Upperside The upperside of the rustic is ochraceous light brown. Its forewing displays some loop-like, slender, dark cellular markings with a broad, somewhat curved, transverse yellow discal band from costa to vein 1. The band does not reach the
termen but broadens posteriorly. The margins of the forewing are irregularly sinuous, with the inner defined broadly with black, and produced outwards in interspaces 3 and 4. Below this, the margin is squarely indented inwards in interspace 2 and outwardly convex in interspace 1. There is a curved series of three black spots. The largest is in interspaces 1, 2 and 3. The apical area beyond the band is black, with a conspicuous yellow subapical spot in interspace 5, and a paler ill-defined similar spot above it in interspace 6. In the posterior, the black area is produced narrowly to the
tornus and encircles a yellow spot near the apex of interspace 2.
